Silicone rubber,CAS#63394-02-5

Silicone rubber is a kind of synthetic rubber, semi-inorganic polymer elastic material containing silica structure in the molecular backbone, which is made of difunctional organosilicone monomer such as dimethyl dichlorosilane after hydrolysis and condensation. Silicone rubber is very similar to ordinary rubber in appearance, but silicone rubber has a high degree of thermal stability and elasticity. The original characteristics are maintained in the range of -60 ~ 300℃. When compressed at high temperature, the shrinkage is very small, and it returns to the original state after the external force is lifted. Silicone rubber has defects such as low molecular polarity, strong hydrophobicity and poor physical properties, so the modification of silicone rubber is the focus of current research. In order to meet the needs of special uses, it is necessary to use special properties of silicone rubber, such as conductive silicone rubber, thermal silicone rubber, heat resistant rubber, oil resistant silicone rubber, shielding silicone rubber, flame retardant silicone rubber, damping silicone rubber, insulating silicone rubber and sponge silicone rubber.
